4 Claims. 1

This application is a division of my copending application Serial No, 536,679, filed May 22, 1944.

This invention relates to hinges generally but is more particularly concerned with cabinet door hinges, the present hinges being especially designed for a knock-down type of sheet metal cabinet in which the doors are adapted to be quickly and easily applied to the cabinet or removed therefrom.

A novel feature of the hinge of my invention is the provision of angle iron hinge members on the door having hinge pintle projections on one flange thereof for detachable engagement in bearing holes provided therefor in hinge bracket members on the cabinet, the other flange On at least one of a pair of angle iron hinge members having a projection arranged in the mounting of the door on the cabinet to be passed through a-notch in the associated hinge bracket member, said notch being so located that the projection can be passed therethrough only in one extreme position of the door with respect to the cabinet, the projection serving, therefore, to prevent accidental and unintentional disconnection of the hinge members.

The invention is illustrated in the accompanying drawing in which Fig. 1 is a perspective view of a sheet metal cabinet, the doors of which have hinges made in accordance with my invention.

Fig. 2 is an enlarged detail, partly in front ele-' vation and partly in vertical section, of the upper right hand front corner of the cabinet illustrating the corner reinforcing cleat as well'as the hinge for the door.

Fig. 3 is a horizontal sectional detail in the plane of the screw It] in Fig. 2, showing how the cleat is fastened into the corner portion of the cabinet with a single screw, and

Fig. 4 is a perspective view of the cleat and door hinge, the dot-and-dash lines indicating the manner of assembly.

The same reference numerals are applied to corresponding parts throughout the views.

Referring to Fig. l, the reference numeral 5 designates the back panel, 6 the top panel, and 1 the bottom panel. 8 and 9 are si-depanels. The top and bottom panels interlock at their rear edges with the top and bottom edges of the back 5 as fully described in the parent application. The side panels 8 and 9 interlock at their rear edges with the side edges of the back panel 5 in the same way.

The top, bottom and end panels, when interlocked with the back in the manner stated, are

2 arranged to be fastened securely in assembled relationship, using only four screws Ill, one at each of the four corners of the front of the cabinet. L-shaped cleats ll, stamped from sheet metal, preferably of medium heavy gauge in relation to the thinner sheet metal used in the panels, are inserted in the corners of the cabinet at the front thereof, and are made to fit snugly in the channels l2, l3 and I4. The ends of the rearwardly projecting flanges of the channels are cut away at these corners as at 30 to permit interfitting the ends of the top and bottom panels with the side panels in the manner shown, and inserting the cleats II. A tapped screw hole l5 in the corner portion of the L, registers with holes l6 punched in the overlapping web portions of the channels I2 and [4, or [3 and M, as the case may be, to permit entering the screws it and threading the same in the holes l5, to draw the cleats up tight when the screws are tightened, and accordingly'make for a rigid cabinet structure, and one which is not apt to get out of shape in service. The cleats keep the corners squared up, and whatever strains are imposed upon the cleats are distributed the full length of the arms thereof in the channels, in which these arms fit snugly, and, ,hence, there is little or no shearing strain imposed upon the'screws [0. The screws merely prevent displacement of the cleats from operativev position.

The cleats l I also provide supports for the doors l1 and [8 of the cabinet. WhileIhave shown two doors, each covering a half of the open front of the cabinet, it should, of course, be understood thatI may provide a single door covering the whole front. Each of the doors is shown as made from a single sheet metal panel, the four edges of which are bent rearwardly and inwardly, to define channels l9, to give the desired strength and rigidity, and also to avoid exposure of any raw edges. A reinforcement 20 is preferably provided in the middle portion of the doors in the form of a dished sheet metal panel, the flanged edges of which are spot-welded to the inner side of the door. A lug 2| is bent outwardly from each of the cleats H, to form a fixed hinge member for cooperation. with a sWinga-ble hinge member .22 on thedoor. Registering slots are punched in the webs of the channels I2 and M, or l3 and [4, as the case may be, forprojection therethrough of the lugs 2|, as indicated in Fig. 2. The hinge members 22 are preferably angle irons formed from sheet metal like the cleats H, and each has a longitudinal reinforcing flange 23, on the end of which a prong 24 is formed. arranged in the assembling of the door on the cabinet to pass freely through a notch 25 in the edge of the lug 21 after the pintle 26 on the hinge member 22 has been entered in the hole 21 provided therefor in the lug 2|. The pin 26 on the upper hinge member 2-? referaniwa trifle shbrter'tnan the" pin 26 on theflo'wer hingememb'er 2am simplify" the assembling operation, the lower, longer pinbeing started in its hole 27 before the upper pin 26 enters its hole. difficulty as would otherwise be involvedii both pins had to be aligned with memes at-ti ie samef time. The pins are preferably alsotaperedoi'i" the ends, as shown, to facilitate assembling. The prong 24 and notch 25 will be provided only-"on the upper hinge, and it should bdclear f16lil'=-Fig-' 2 that, after the door is hung and the prong 7.4 is disposed under the lug 2| and the door is s-wung forwardly from the dotted line position shown in Fig. 1 and corresponding to ,thatin Fig. 2, the d'dor: is lo'ck'e'd against accidental displapement or; hinges, becatisie' the men-e2 3- will strike: the atten? 6f" the" liig" 2i and" prevent upward displacement of tlidotir" from d eran've positi in an iqjsiinens ere-asp t at 111m area in do lirlesiii 1, vanerenije 2 2'4 isi'nregi'ster w I Y the rustic}; 25' and isthe efore moraine fire en the fiance: asifidiea'tee b3 meant-mant es lines" in Fig-Q 4'. epperand owerrearic rnere; p
